Objectives: To determine whether cigarette smoking is associated with the abnormal retention of residual sperm cytoplasm in infertile men.
Methods: Semen samples were obtained from 87 consecutive non-azoospermic men with idiopathic infertility (18 smokers and 69 nonsmokers) and from 20 men presenting for vasectomy (fertile controls). Standard semen parameters and the percentage of spermatozoa with residual cytoplasm (on Papanicolaou smears) were recorded.
Abnormal retention of cytoplasmic residues by human spermatozoa is associated with the generation of reactive oxygen species (ROS) in semen and defective sperm function. We have examined the effect of varicocelectomy on the retention of residual cytoplasm by human spermatozoa. Clinical reports of 43 men who underwent microsurgical varicocelectomy at our institution during a 1 year period beginning July 1996 were reviewed.

Design: Prospective data gathering.
Setting: University infertility clinic.
Purpose: Following microsurgical vasoepididymostomy as many as 85% of men have sperm in the ejaculate, yet only 30 to 50% will spontaneously father children. We examined the possibility that there may be concomitant abnormalities in the prostate and seminal vesicle, which may be associated with low pregnancy rates.
Materials And Methods: Transrectal ultrasound was performed in azoospermic men with suspected epididymal obstruction, excluding those who had undergone vasectomy, to identify abnormalities of the seminal vesicles and ejaculatory ducts.
